1.	Axial T2W MR image nine months post surgery reveals postoperative seroma (arrow on JPEG image). Repeat surgery at our institution 3 months following the MR examination revealed a cystic space and histological examination revealed focal foreign body giant cell inflammation in fibroadipose tissue. No residual tumor was identified.
2.	Representative photomicrograph from 'cystic' space reveals space lined by denuded epithelium and fibrocollagenous wall with giant cells. (Original magnification, X120, H-E Stain). Prolonged retention of some postoperative seromas may be secondary to such spaces formed after surgery.
